IMPROVEMENT IN AN'lMAL-TRAPS.

Specification forming part of Letters Patent No, 43,030, dated June 7, 1864.

-Improved Mode of Constructing Self-Setting,

Animal-Traps; and I do hereby declare that 'the following is a full and exact description thereof, reference beinghad to the 'accom-V fpanying drawings, and to the letters of reference marked thereon.

The -na-ture of; myinventon consists in so constructing-a trap that it'will be all the timeset or open and ready 'forthe animal to pass in, but utterly impossible to get out. a

Io enable others skilled in the art to inake and use my invention, I will proceed to de scribe its construction and operation.

I construct the box or body of the trap of sheet-.metal or other material, 'as shown` at letter A. In the inside of this box or body L place a shutter, as shown at B, at one end of which is attached a wire or pin projecting at the sides, as at a a.. 'These'. projecting ends pass through the sides of the body of' the box, as shown at b. There is a tread-le, as shown .at C, to which is attached a cross-piece, the ends projecting, as`at g g, which pass through the s idespf the box at f. This treadle is placed in, the box, theslxort en d being underneath the shutter B. The end of the treadle, is turned under alittle, as at 0, and acrosspiece or fulcrun'i, g g, is placed on the treadle C, so when itjilzs its end O will strike 'on the underneath side "of shutterB, just back of eross`piece a a, shutter B being sutciently long to'reach over or lie ou the treadle. .i

W is a flange ou the -end of the trap.

'm is the entrance to the trap. When the. trap is completed, as sliown'and described, an opening is to be madein a box and the trap placed in it, as shown at Figure 1, Fig.5 being the box in which the trap'is placed.'V The animal-.will enter at m and pass through the trap into the box whe-rethe baitwill' be placed. 0n its return the animalwill"havetostep 011 the treadle at M, when the front 4end of the treadle will instantly throw up the shutter B cross-piece g g of r and effectually shut up the passage before the ani1nal,aud as soon 'as the animal is oiof the treadle the shutter B will drop to its place again, leavingthe passage open, so that' those 'outside'inay pass in all the time, but out never.

These trapsfmay be made anyl size from a mouse to a wolf brother` animal.

' I am aware that attempts have been made to construct a trap lto remain open only when the thingcaught attempted to go out, but they are complicated and' not durable.

Wha-t1 claim as lnyinvention, and desire to *secure by Letters Patent of the United States, 1S,- f i The "combination and 'arrangement `of the shutter B with .the treadle-.lever C, as shown and described, for the purposessetforth.
